1/4 in. Tube OD x 3/8 in. Tube Stub OD - Reducer Tube Stub Connector - Double Ferrule - 316 Stainless Steel Compression Tube Fitting

Commonly used on: Instrumentation, high pressure and temperature, cryogenic service, and process and control systems where high quality tube fittings are required. Provide a highly reliable, leak proof and torque free seal on all tubing connections.
These double ferrule tube fittings have been designed specifically for the many demanding applications such as chemical, petroleum, power generating, pulp, paper and various types of manufacturing industries.

Reducer tube fittings incorporate a tube stub end that allows a designer/fabricator the ability to upsize or downsize a tube connection within a tube system in both the single and double ferrule designs.

Connects fractional tube to fractional compression end port.

Many tube fittings have a male or female pipe end. These ends sometimes have a lower pressure rating than the pressure rating of the tube fitting end. The ratings shown above are based on ASME B31.3-1999.
Female pipe ends have lower ratings than male pipe end in a given size due to the inner and outer diameters of the female threads being larger than those of the male pipe ends.
